My client is getting the same error as mentioned in (http://answers.laserfiche.com/questions/109063/laserfiche-license-Manager--an-invalid-argument-was-provided2032 ). After rebooting their server they new receive the error "An invalid argument was provided (2032)". We are able to move past it but when trying to update the master license, it gives us the same error. The event logs state the same thing, "An invalid argument was provided" is the only thing it says in the event log entry. They are on version 8.3.1 of the license manager.
